I didn't know this theorem about the bounded category of coherent modules. I'm used to thinking that perfect modules are better than D^b(CohX) when X isn't smooth so this is really surprising to me. I think I maybe able to use this observation to prove what I want, I'll have to check. One final subtlety, which I added in an edit and maybe you didn't catch is that I want to consider matrix factorizations of possibly infinite rank... because otherwise the notion of compact doesn't make sense at all. I noted the 1-d case too. | |
